Composite risk spans 88.7–93.8/100 across 3 counties; most-cited top hazard is Hail (in 2 of 3).
Natural-hazard exposure for Aurora from the U.S. Federal Emergency Management Agency's National Risk Index (FEMA NRI March 2023). NRI is an expected-annual-loss composite calibrated on 1996–2019 historical losses, published at the U.S. county grain. See methodology §17.
Aurora spans 3 counties. We list each separately because hurricane, flood, and fire risk varies meaningfully across county lines — manufacturing a single “city-level” risk score would hide that signal.
